I will use the ninja world to aid my cultivation of immortality.

Now that his cultivation has made another breakthrough, Naraku is not only happy about the improvement in his strength, but also happy that he is one step closer to the Foundation Establishment stage.

To celebrate inner joy.

After Naraku returned to Hoshinin Village after testing the improvements brought about by the sixth level of Qi Refining, he brought Nonou and Natsumi together that very night.

Chapter 124 Immortal Seal

The next afternoon.

"Immortal Seal?"

After a night of turmoil, Nono and Natsumi finally calmed down by the afternoon and looked at Naraku in surprise.

Naraku looked with great interest at the two women who had just finished showering and were simply wrapped in bath towels, and couldn't help but open his arms.

Seeing Naraku's actions, Nono and Natsumi immediately understood what he meant.

The two of them weren't embarrassed at all, and naturally stepped forward and sat on Naraku's lap, one on each side.

"You haven't mentioned the Immortal Seal yet?"

Feeling the hand that was acting up on her body, Nono quickly pressed it down.

She had only just gotten up; if she were to be disturbed again, she would probably have to rest until tomorrow.

On the other side, Xia Rixing's face was flushed, but she did not stop the hands that were also messing with her. Instead, she leaned closer to Naraku's chest.

Compared to the busy Nonou, although she was appointed as the head of the military department, she had much less free time.

After all, Liang Shanbo's actions decreased significantly after the plunder of the Land of Earth, which meant that Xia Rixing spent most of his time cultivating.

So even if she has to go through all that trouble again, as long as her body can handle it, she's actually quite willing to.

"The 'Sage Seal' is a Sage Technique I developed. You know Tsunade, Jiraiya, and Orochimaru, the three legendary Sannin of Konoha, right? Their summoning beasts came from the so-called Three Great Sacred Lands, and each of these three summoning beast clans possessed a Sage Technique lineage."

Although Naraku's hands were causing trouble, he didn't forget to explain the Immortal Seal to the two women.

When Naraku signed the contract with Death Scorpion, he associated Death Scorpion's condition with the inheritance of Sage Techniques.

Therefore, upon returning to Xingren Village, he arranged for numerous True Qi Shadow Clones to be responsible for the development of Sage Technique inheritance.

Now, the development of this immortal technique has come to fruition.

This is what we now call the "Immortal Seal".

The name "Immortal Seal" clearly indicates that it was inspired by the "Yin Seal".

The same is true.

Naraku had many ideas during the development of the sage technique inheritance, but he ultimately chose to draw on the principle of the "Yin Seal".

The most typical example of the "Yin Seal" is Tsunade.

This seal can store accumulated chakra within it, which can then be released and used when needed.

The same applies to the "Immortal Seal".

However, compared to the Yin Seal, the Immortal Seal has more functions.

In addition to storing the chakra accumulated over time, the 'Sage Seal' can also autonomously absorb the spiritual energy of heaven and earth, and then automatically fuse the absorbed spiritual energy with the stored chakra into Sage Chakra.

That's right.

Naraku's "Immortal Seal" is a rather foolproof method of inheriting immortal techniques.

Or to be more precise, he placed all the difficulty on the setting of the "Immortal Seal," leaving users with only very simple operations.

Basically, once he sets up the "Sage Seal," the user only needs to inject chakra into it and wait to absorb enough spiritual energy. Then the two will merge into Sage Chakra, allowing the user to freely enter Sage Mode.

In terms of inheritance, the "Immortal Seal" setting, which incorporates all the difficulties, is naturally not something that ordinary people can learn. In fact, only Naraku, a cultivator, can master it.

However, in terms of usage, the "Sage Seal" is definitely safer and simpler to operate than the Sage Techniques passed down in the ninja world.

This is exactly what Naraku wanted.

He developed the Sage Art inheritance only to improve the strength of the Death Sasori clan and Nono, not to add a new Sage Art inheritance to the ninja world. Naturally, the safer and simpler the operation, the better.

After listening to Naraku's explanation of the "Immortal Seal," Nono and Natsumi were extremely surprised.

The main reason was that neither of them had ever heard of the system of immortal arts inheritance before.

In Naraku's explanation, the inheritance of Sage Techniques is clearly superior to ordinary inheritances such as Ninjutsu, Taijutsu, and Genjutsu, and can even be regarded as a powerful bloodline limit.

"Then let me test just how powerful this immortal technique inheritance is!"

Nonou was very proactive. After learning about the power of the "Immortal Seal," she immediately turned her eyes to Naraku and passionately embraced his neck, giving him a hot kiss.

"I want one too!" Xia Rixing refused to be outdone, and as soon as the two separated, she immediately offered herself up as well.

"Don't worry, the 'Immortal Seal' was originally prepared for you."

After tasting the two different flavors, Naraku smiled and patted the two women's pert buttocks, telling them to get dressed.

Driven by their anticipation of the "Immortal Seal," Nono and Natsumi acted swiftly, quickly changing their clothes. Then, Naraku embraced the two women's supple waists and used the "Shrinking the Earth to an Inch" technique to leave the room.

brush!

In a flash, when Naraku and his two companions reappeared, they were already in their private training ground.

"Nonou, you go first!"

Naraku loosened his grip on the two women's waists, allowing Nono to sit cross-legged on the grass.

After Nono sat down obediently, Naraku sat cross-legged opposite her, raised his index finger, and touched the other's forehead.

True energy flowed from his fingertips to Nono's brow, like threading a needle, beginning to weave its incredibly complex 'Immortal Seal'.

For a full quarter of an hour, when Naraku withdrew his finger, a touch of crimson appeared between Nono's eyebrows.

Naraku said to Nonou, "Normally, at the normal pace, it would take at least several days of absorbing spiritual energy to enter Sage Mode."

However, to allow you to experience Sage Mode first, I will actively guide spiritual energy into the 'Sage Seal.' You only need to inject your own chakra into the 'Sage Seal' as well.

"Understood!" Nonou nodded.

Next, Naraku pointed at the crimson surface manifested by the 'Immortal Seal' once more, guiding the spiritual energy of heaven and earth into it.

Following Naraku's instructions, Nonou continuously poured the chakra she had refined into the "Immortal Seal".

Xia Rixing watched the whole process very attentively.

After all, once Nono has had her turn, she'll be next.

As Naraku guided the spiritual energy into the 'Immortal Seal,' his divine sense could clearly perceive the rapid fusion of the spiritual energy entering the 'Immortal Seal' with the chakra injected by Nono.

After a short while, Naraku withdrew his finger.

"Alright, now all you need to do is unlock the 'Immortal Seal' to enter Sage Mode!" Naraku smiled at Nono.

"I'll give it a try!" Nonou, who had stopped refining chakra, began to operate with anticipation.

Unlocking the "Immortal Seal" is easy, like an automatic switch; it can be done by triggering the core node with chakra.

boom! ! !

The moment Nono successfully broke the 'Immortal Seal', the crimson dot between her brows instantly blossomed into a red lotus flower.

Correspondingly, Sage Chakra, formed by the fusion of spiritual energy and chakra, rapidly surged out from within the Sage Seal, sweeping across Nonou's limbs and bones.

Since it was her first attempt, Nonoyu did not control the sudden surge of Sage Chakra very well, causing the power to leak out and the place where she was sitting to shatter, spreading spiderweb-like cracks.

Chapter 125 Immortal Technique Inheritance

"What amazing chakra!"

Nonou's beautiful eyes widened in amazement at the Sage Chakra surging into her body.

brush!

Use your legs to exert force.

Nono instantly became a blur, and in a flash, she appeared a hundred meters away, her speed far exceeding anything she had ever done before.

Boom! ! !

Realizing that her speed had greatly increased, Nono was excited and couldn't help but test her super strength technique.

When she slammed her fist into the ground, the earth within a radius of over a hundred meters was immediately struck, shattered, and collapsed, forming a huge crater resembling a meteorite impact.

"Amazing!"

The tremors and shockwaves from the collapsing earth swept towards Naraku and Natsumihoshi.

Xia Rixing raised her hand to shield herself, unleashing chakra to block the impact. Once the impact subsided, she looked back at the approaching figure, her mouth agape in shock.

She was naturally familiar with Nono's superhuman strength.

However, compared to Nono's previous superhuman strength, looking at the huge pit in front of her with a diameter of over a hundred meters and a depth of over ten meters, how could Xia Rixing not see that Nono's superhuman strength had increased dramatically compared to the past?

Compared to Xia Rixing's shock, Naraku was much calmer.

As the developer of the "Immortal Seal," he is naturally most aware of the enhancements it brings.

The Sage Mode of "Sage Seal" is similar to the Sage Mode of Mount Myōboku, both of which can dramatically enhance the power of one's ninjutsu, taijutsu, genjutsu, etc.
